In 1964, the Washington State Department of Transportation (WSDOT) created a new numbering system, the State Route system, out of the existing Primary State Highways (PSH) and Secondary State Highways (SSH) system. The new system, called State Routes or Signed Routes, consolidated and created a more organized and systematic method of numbering the highways within the state. The system also introduced accordance with the new Interstate Highway system, with the creation of Interstate 5 within the state.
